배장호,김연충,원충연 成均館大學校 科學技術硏究所 1999 論文集 Vol.50 No.1

This paper proposes a linearization technique for the space vector modulation method, which increases the linear control range of inverter up to the 6-step inverter. This method is based on fourier series expansion of the desired output voltage of the inverter to calculate the compensation angle in continuous switching mode and holding angle in discontinuous switching including the 6-step mode respectively. The numerical data of these angles which are used for compensation of fundamental voltage in overmodulation range. Therefore, it is possible to obtain the linear control and the maximized utilization of PWM inverter output voltage.

The purpose of this study is to exhibit fundamental data which can apply to quality and process management of structure concrete using special cement in the construction field investigating strength prediction by maturity method of concrete according to cement types. The activation energy value was derived from the experimental study that experimental factors were selected as W/C ratio of 45%, the kinds of cements of 3 levels of O.P.C, H.B.C, H.S.C and curing temperature of 3 levels of 5℃, 20℃, 35℃. Also, after investigating relationship between compression strength and equivalent ages of concrete according to cement types, the strength prediction was investigated by maturity method. As the above of results, differences between the prediction strength by strength prediction equation and the actual measurement strength were lower, therefore it is considered that the strength prediction by maturity method is possible not only concrete using normal portland cement but also concrete using special cement.

Objectives : We performed this study to assess the needs of the chronically mentally ill(CMI) from the perspectives of the consumers(patients) and the providers(therapists) and to compare the differences between them. We also aimed to find met needs and unmet needs and then to determine the priority of the mental health services for the CMI. Methods : 165 patients and 19 therapists were examined with need assessment tool which had been developed by authors. Through statistical analysis, we evaluated the degree of problem, the degree of intervention, the relative degree of problem, and the degree of demand in each areas of needs, and compared the differences between patient group and therapist group. After then met needs and unmet needs from the perspectives of each group were revealed. Results : 1) There were differences in the assessment of needs between patients and therapists. 2) The more problem areas assessed by patients were finances, mental health, occupation, and leisure life in order of higher ranks. While occupation, leisure life, mental health, and finances were assessed as highly ranked problem areas by the therapist group. 3) Patients perceived that they were given more helps from others in the areas of mental health, physical health, accommodation, and relation to family than other areas. From the perspective of therapists, the areas of needs such as mental health, basic knowledge, occupation, and interpersonal retation were highly ranked intervention areas. 4) The demands for daily living skill, occupation, finances, accommodation were ranked highly by patient group. Highly demanded needs assessed by therapist group were mental health, occupation, interpersonal relation, and basic knowledge. 5) Unmet needs assessed by patient group were occupation, finances, and accommodation, while by therapist group, occupation. Conclusions : The needs of the CMI were assessed and identified by the consumers(patients) and providers(therapists) with the same tool. The differences between two groups were revealed. The most important unmet need of the CMI was occupation. These results can be used to plan the priority of mental health services and policies.

Column that Packed with Montz Packings regularly and dumped Packing with Pall ring, Hiflow ring and Hackette have been represented high efliciency in Vacuum rectification and absorption. The new correlating of these relationships based on the numerous results has been developed for process calculation and design. The results of laboratory or experimental pilot plant can be adopted dircetly for scale-up.

석탄회를 이용한 제올라이트의 합성 및 암모니아성 질소 흡착

류완호,박찬교,배장순 한국공업화학회 2004 공업화학 Vol.15 No.1

국내 석탄 화력발전소에서 폐기되는 석탄회를 이용하여 제올라이트를 합성하였으며, 이를 이용하여 폐수 중 암모니아성 질소 제거용 흡착제로서의 활용가능성을 조사하였다. 실험결과 산에 의한 전처리 과정이 중요하고, 4M-NaOH, 반응시간 4 h, pH 7~9.5에서 합성한 제올라이트가 가장 우수한 흡착성능을 보였으며, 이는 상업용 5A형 제올라이트와 비슷한 80%의 흡착성능을 보였다. Synthetic zeolite was prepared from coal fly ash which had been abandoned from a domestic power plant as wastes, and was investigated as an absorbent for removed of ammonia from the waste water. The results suggest that pH control step in the synthesis process was an important factor for the removal capacity due to the presence of alkaline materials such as CaO and MgO in fly ash. Accordingly the zeolite synthesized at 4 M-NaOH and 4 hrs under controlling the pH7-9.5 showed the removal efficiency of 80% as much as the commertial one at its highest ate.

본 연구의 목적은 태권도 참여정도와 목표지향 및 인지된 자유감의 관계를 규명하는데 있어 연구대상은 2003년 현재 서울?경기 지역에 거주하며 태권도 수련을 하는 20세이상의 성인 남 228명, 여 272명, 총 500명을 대상으로 하여 목표지향을 측정하기 위해 Duda(1989)와 Nicholls(1989)에 의해서 개발된 TEOSQ를 성창훈이(1995)이 번안 작성한 설문지를 사용하였고 인지된 자유감(perceived freedom)을 측정하기 위해서는 여가진단 도구(Leisure Diagnostic Battery; LDB, Witt & Ellis, 1987) 원형중(1989)이 한국의 실정에 맞게 번안 검증하여 재개발한 여가진단 도구중에서 인지핀 자유감 척도를 사용하였다. 자료분석을 위해 사용된 통계분석은 프로그램인 WNDOWS용 SPSS/PC+ 10.0버전 을 이용하여 빈도분석(Frequency), 신뢰도분석(Reliability analysis), 일원인량분석(one-way ANOVA), 중다회귀블석 (multiple regression analysis)을 실시한 결과 첫째, 인구통제학적 특성에 따른 목표지향, 인지된 자유감의 차이는 부분적으로 나타났다. 둘째, 태권도 수련정도와 목표지향 및 인지된 자유감은 부분적으로 영향을 미치는 것으로 나타났다. 셋째. 태권도 수련자의 목표지향은 인지된 자유감에 영향을 미치는 것으로 나타났다. A study on the relation among the level of practice of Taekwondo, goal orientation and perceived freedom The purpose of this study is to look into the relation among the level of practice of Taekwondo, goal orientation and freedom. The, survey was conducted against 500 subjects, which consists of 272 female adults and 228 male adults above 20 who are practicing Taekwondo in the Seoul and Gyeonggi areas as of 2003. For evaluating the goal orientation, we used two research tools: 1) for evaluating the goal orientation, the questionnaire that Seong Chang-hun(1995) adapted the TEOSQ(Task and Ego Orientation in Sort Questionnaire) which was developed by Duda(1989) and Nicholls(1989), 2) for evaluating the perceived freedom, the perceived freedom scale which is one of the tools that Won Hyeong-jung(1989) adapted, verified and re-deveoped the LDB(Leisure Diagnostic Battery; Witt & Ellis, 1987) in consideration of domestic conditions. For analysis, we performed frequency analysis, reliability analysis, one-way ANOVA, and multiple regression analysis against the data with SPSS/PC+ Version 10.0 for WINDOWS which one of popular statistical analysis programs. Based on the above research procedure, we could conclude as follows: First, difference between the goal orientation and the perceived freedom of Taekwondo practicians was partially shown on the basis of demographic characteristics. Second, the level of practice of Taekwondo partly influenced their goal orientation and perceived freedom. Third, their goal orientation influenced their recognized freedom.
